[jira] [Updated] (FLINK-9317) Async I/O API Example For Scala has
Variable Name error
[ https://issues.apache.org/jira/browse/FLINK-9317?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Yazdan Shirvany updated FLINK-9317:
-----------------------------------
Description:
h2. Async I/O API Scala Example has duplicated {{resultFuture variable with different data type.}}
{{resultFuture: ResultFuture[(String, String)]}}
val resultFuture: Future[String]
{{this cause error on compile as variables have same naming.}}
{{In order to example works properly we need to update variable names to be distinct,}}
{{```}}
override def asyncInvoke(input: (String,String, String), resultFuture: ResultFuture[(String,String, String, String)]): Unit = {
// issue the asynchronous request, receive a future for the result
val *resultFutureRequested*: Future[String] = Future
{ // client2.query(str) client.getAccountReferenceId(token, input._1) }
// set the callback to be executed once the request by the client is complete
// the callback simply forwards the result to the result future
*resultFutureRequested*.onSuccess {
case result: String =>
{ resultFuture.complete(Iterable((input._1, input._2, input._3, result))) }
}
}
{{```}}
